My tcl split ac works for 5 min, then gives e5 code.
E5 s a communication error between the indoor and outdoor units. It is stated in the service manual that the wiring between the indoor and outdoor has probably separated at one end of the terminal block. Most of the time however, it is usually a failure of either the indoor or outdoor electronic boards. A multimeter and knowledge of how to read "communications voltages is required. The machine will continually assess itself electronically to make sure all components are working properly. If after a given amount of attempts to communicate with the outdoor unit the machine still cant "talk" to the other 1/2 , it will show an E5 error and shut itself down. You could try switching off the power at the isolator or meter box for at LEAST 15 minutes and then turn back on to see if it resets. This sometimes works. Do not, just switch off and switch straight back on again.
